A program that computes functional enrichment across groups of genomes..
🔙 To the main page of anvi’o programs and artifacts.
This program computes functional enrichment across groups of genomes and returns a functional-enrichment-txt file.
Please also see anvi-display-functions which can both calculate functional enrichment, AND give you an interactive interface to display the distribution of functions.
You can use this program by combining genomes described through external-genomes, internal-genomes, and/or stored in a genomes-storage-db. In addition to sources for your genomes, you will need to provide a groups-txt file to declare which genome belongs to which group for enrichment analysis to consider.
How does it work?
Aggregate functions from all sources. Gene calls in each genome are tallied according to their functional annotations from the given annotation source.
Quantify the distribution of functions in each group of genomes. This information is then used by
anvi-script-enrichment-statsto fit a GLM to determine (1) the level that a particular functional annotation is unique to a single group and (2) the percent of genomes it appears in in each group. This produces a functional-enrichment-txt file.
You can use it with a single source of genomes:
You can get a tab-delimited matrix describing the occurrence (counts) of each function within each genome using the
